Should federal law cap annual primary spending growth below GDP growth?

This debate hinged on a critical tension between Pro's theoretical framework of "well-designed" hard caps and Con's empirical evidence from real-world implementations. Pro opened with a sophisticated argument distinguishing growth-based caps from strict balanced budget amendments, citing Colorado's TABOR and Germany's debt brake as successful models. However, this strategy backfired when Con systematically dismantled both examples.

The decisive turning point came in Round 2, when Con documented that Germany's debt brake contributed to coalition collapse in 2024 and that Colorado's TABOR—far from being a success story—has created a "governance catastrophe" where the state simultaneously cuts essential services while issuing refund checks. Pro's attempt to pivot to the Swiss model in Round 3 was strategically sound but came too late to recover credibility lost on the primary examples.

Con consistently demonstrated superior engagement, directly addressing Pro's specific claims about flexibility mechanisms with counter-evidence showing how these mechanisms fail in practice. Pro's closing argument attempted to reframe TABOR as a poorly designed cap, but this concession undermined the opening's central claim that TABOR demonstrated successful implementation.

Both sides exhibited strong logical reasoning, but Con's evidence was more current and directly responsive to Pro's claims. Pro's theoretical distinctions between cap designs were analytically sound but lacked compelling real empirical validation.
